Feature Request: Support OAuth 2.0 in Custom GPT Actions

As an Enterprise user, I would love to see OAuth 2.0 support in Custom GPT actions.

Many APIs that are essential for enterprise use—such as Microsoft Graph API for Outlook, Teams, and OneDrive—require user-level authorization via OAuth 2.0.

Adding this capability would allow GPTs to act as true personal agents, enabling secure, user-authorized interactions with real data.

This is especially important for business workflows where secure access to calendars, emails, or cloud documents is required.

Please consider enabling Custom GPTs to authenticate using OAuth 2.0 flows such as authorization code or device code.

Thank you!
